Dendrobium candidum water-planting device

Abstract

The invention discloses a dendrobium candidum water-planting device, which comprises an incubator. A controller is arranged on an outer wall of the incubator; a concentration sensor is arranged on an inner cavity wall of the incubator; outer ends of rotary rods penetrate through the incubator so as to be connected with motors; telescopic rods are inserted into guiding pipes; nuts are in threaded connection onto the telescopic rods and are located on the upper sides of the guiding pipes; the upper ends of the two opposite telescopic rods are connected through a cross rod; infrared distance measurement sensors and an illuminating lamp are arranged on the lower end of the cross rod; and a mother liquor tank is arranged at one side of the incubator. According to the dendrobium candidum water-planting device, the motors work at regular times, and a nutrient solution in the incubator is stirred through stirring blades, so that the flowability is improved, the nutrition is more balanced, a value measured by the concentration sensor is more accurate, and liquor supplement of the mother liquor tank can be carried out conveniently; and through data measured by multiple groups of infrared distance measurement sensors and the height of the telescopic rods, the height of dendrobium candidum can be known without the need for manual measurement.

Description

technical field [0001] The invention relates to the technical field of hydroponic culture of dendrobium candidum, in particular to a hydroponic device of dendrobium candidum. Background technique [0002] Dendrobium officinale, also known as: Black knot grass, Yunnan iron bark. Belonging to the order of Micros, it is a perennial epiphytic herbaceous plant of Orchidaceae. Stems erect, cylindrical, 9-35 cm long, 2-4 mm thick, sepals and petals yellow-green, nearly similar, oblong-lanceolate, about 1.8 cm long, 4-5 mm wide, flowering period March-June. Over the years, Dendrobium has mainly relied on wild resources, long-term excessive collection and people's destruction of the natural environment, coupled with its low reproductive rate, and the depletion of natural resources. At present, Dendrobium officinale has become an endangered plant and is listed as a national key protected medicinal material variety. In order to protect the reproduction of this species and realize the...

Problems solved by technology

Although the cultivation technology of Dendrobium officinale has made great progress, there are still problems such as high technical difficulty, high investment cost, long production cycle and high risk in cultivation, and it cannot be popularized like ordinary Chinese medicinal materials.

[0003] There are also Dendrobium candidum hydroponic devices on the market, such as the patent No. CN201420239053.4. However, the fluidity of the nutrient solution in the culture bed is poor, which is not conducive to the growth of Dendrobium candidum, and will affect the accuracy of the concentration sensor inside. The height of Dendrobium candidum is generally measured manually or observed with the naked eye, which is very inconvenient. For this reason, we design a hydroponic device for Dendrobium candidum
